Linkswitch-CV LNK626 DCON
Posted by: nishi

Hello,
I'm trying to design a circuit using Linkswitch-CV LNK626.
When I enter the parameters in PI Expert Online, the message "DCON (Output Diode conduction time) should not be less than 4.5 us." Is displayed.
When I experimented, it was a short time when the load was light.
Also, maximizing the load increased the time. The DCON time changes depending on the load.
The datasheet states that the feedback-pin Sampling Delay time is typically 2.75us.
Does it have to be 4.6us or higher even under a light load?
Or should it be 4.6us or more at maximum load?
When should it be 4.6us?
Also, why is DCON 4.6us?
Thank you
Hi,
Could you please send me the spreadsheet so that I can re-create your design on PI Expert as well? Thanks.
